"VG" can mean different things to different people. Other factors bringing the price down might include: the price being clipped; just a poorer (i.e. VG-) jacket generally; or perhaps the top page edge a little faded. Those points aside, your copy is a 2nd impression --and this devalues it (in comparison to a 1st edition/1st impression) more than anything. £10 perhaps? HoME books, in general, aren't really selling that well I don't think.
